Public cooperation in helping to develop and maintain healthy and attractive trees is encouraged. MAINTENANCE OF PARKWAY TREES The Parks, Beaches and Recreation Department will trim the parkway trees on a rotation schedule. An effort will be made to trim most of the parkway trees on a two year cycle. If the rotation trimming is completed in less than two years, more frequent trimming will be done on certain trees and in view areas. Public safety such as low branches and heavy foliage will be given priority over view trimming. An effort will be made to trim parkway trees on the Peninsula and parts of Corona del Mar during the fall and winter due to heavy traffic during the summer. Trimming schedule will be altered to avoid trimming streets with flowering street trees during their blooming time. This will apply to streets having a large number of flowering trees, not to one or two trees on a street.
